WATER-CLOSET CISTERN.

SPECECATIONorming part of Letters Patent No. 339,062, dated Icare-h 30, 1886.

Application fled October 14, Selial No. 179,327. (No model.)

To @ZZ whom it r11-ay concern:

Be it known that I, J osnrn KAUFMANN, a

drawn down tightly on its seat a, and held in position by means of the nut f, a washer, g,

citizen of the United States, and a resident of being inserted between the nut and plate for 55 New York,in the county of NewYork and State the purpose oi' rendering thcjoint water-tight. of New York, have invented certain new and Asuitable packingsuch, for instance, as red useful Improvcmentsin Water-Closet Oisterns, leadis inserted between the edges of t-he of which the l'ollowing is a specification. plate C and shoulder a, for the purpose of pre- My invention relates to an improvement in venting any water from passing between them 6o water-closet cisterns, the object ot' the same befrom the cistern A into the box B.

Io ing to provide adevice of this character which The plate C is provided with another openshall be simple and economical in construcing,having formed around it the hub or iiange tion, durable and efficient in use, and so ar- 7l.,providedwithafemalescrew-thread,through ranged as to prevent any stench or smell from which passes the overflow-pipe E, extending 6 5 passing through the cistern and permeating from the upper portion of the cstcrn into the the house; and with these ends inlview myinlower portion ofthe box B.

vention consists in certain novel :features of The box B has formed in the bottom an construction, as will be hereinafter described, opening, around which is constructed an npand pointed out in the claim. wardly-extcnding flange, t', the upper edge of 7o In the accompanying drawings, Figure l represents a longitudinal sectional View of my improved cistern. Fig. 2 is a top plan view thereof.

A represents the outer casing of a water closet cistern, constructed of any suitable inaterial and of any suitable dimensions, and having the Servicebox B extending below the saine and cast integral therewith.

The service-box B is formed with a shoulder, a, on which is adapted to rest the servicebox plate C, as shown in Fig. l of the drawings. rlhe plate C is formed with a central opening, b, for the passage of the water from the oistern into the service-box, said opening having formed around it an upwardly-extending ilange, c, Aforming a valve-seat, as hereinafter described. rlhis plate is also provided with an opening` for the admission of the cistern snpplypipe D, which latter is provided on its npper end with an ordinary valve operated by a lever and iioat, (not showin) said latter opening being provided with a downward]y-projecting liange or hub, d, encircling the supply-pipe D.

The bottom ol' the box B is provided with an opening having a hub or flange, e, formed around it, also encircling the suppl y-pipe D, which is threaded to engage with a thread formed in the hub or flange c. rIhis pipe is also threaded above the plate C, for engagement with the lock-nut f. It will be readily understood that by turning the pipe D,which is threaded in the hub c, the plate C will be which is somewhat higher than the lower end of the overiiow-pipe E. From the opening in the bottom ol" the box leads a pipe, to the basin of the water-closet, adapted to carry the water from the cistern thereto and wash 7 the same.

On the top of the ilange c, formed around the central opening in the plate C, rests the valve F, preferably made of lead, and having a spindle, Z, passing down through the same, the under side of said valve F having a washer secured thereto by means of a lock-nut, in, iitting on a sleeve, a, secured to the spindle, for the purpose of allowing it to rest snugly on its seat. The upper end of the spindle Z is 8 attached to the lever in the closet, by means of which said valve is operated, the lower end of the spindle being passed down through an opening, o, formed at the junction of the arms p, extending across the lower portion of the valve-opening b, said lower end ef the spindle having a pin, i', passing through it, for the purpose of preventing the spindle from being pulled ont at the opening 0.

Having now described the construction of 9 my improvement, I will set forth its operation.

NVhen the lever of the closet (not shown) is pulled up, the valve F is raised from its seat, allowing the water in the cistern A to flow down through the opening I) into the box B, the valve being guided in its vertical movements by means of the spindle 7. rllhe water flows down through the opening in the bottom of the box through the pipe k to the basin of the closet, and continues so to ilow until the lever is lowered, and the valve F allowed to rest on its seat c. After the valve F has resumed its position on its seat the flow of water from the oistern will be cheeked, and the water in the box will ow down the pipe 7c until it reaches the level of the upper edge of the flange i, which, as before stated, is somewhat above the bottom of the box, thus allowing a quantity of the water to remain in the lattern As the upper end of the flange t' is higher than thelower e'nd of the overflow-pipe E, the level of the water is also above the said lower end of the overflow-pipe, and therefore keeps it constantly submerged. By these means the stench or smell arising from the closet-basin when in use is prevented from passing up through the pipe k into the box B, and up `through the overow-pipe, the water in the box tightly sealing the lower end of the latter.

I would have it understood that I do not limit myself to the exact construction and arrangement of parts shown and described, but

hold myself at liberty to make suoh changes as fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The oistern A, formed integral with the box B, and Constructed with the shoulder a, the plate C, constructed with the opening b and flanges c cl h, the valve F, the outlet-pipe 7c, and overflow-pipe E and inlet-pipe D, the said box being formed with the hubs e and t', the upper edge ofthe latter being higher than the lower end of said overliow, substantially as set forth.

Signed at Brooklyn, in the county of Kings and State of New York, this 12th day of October, A. D. 1855.
